In terms of overall gaming performance, the graphical capabilities of the AMD FirePro W9000 are very slightly better than the Nvidia GeForce GTX 660 Zotac AMP Edition.

The GTX 660 has a 71 MHz higher core clock speed than the FirePro W9000, but the FirePro W9000 has 48 more Texture Mapping Units than the GTX 660. As a result, the FirePro W9000 exhibits a 41.1 GTexel/s better Texture Fill Rate than the GTX 660. This still holds weight but shader performance is generally more relevant, particularly since both of these GPUs support at least DirectX 10.

The GTX 660 has a 71 MHz higher core clock speed than the FirePro W9000, but the FirePro W9000 has 8 more Render Output Units than the GTX 660. As a result, the FirePro W9000 exhibits a 6.1 GPixel/s better Pixel Fill Rate than the GTX 660. However, both GPUs support DirectX 9 or above, and pixeling performance is only really relevant when comparing older cards.

The GTX 660 was released less than a year after the FirePro W9000, and so they are likely to have similar driver support for optimizing performance when running the latest games.

Both GPUs exhibit very powerful performance, so it probably isn't worth upgrading from one to the other, as both are capable of running even the most demanding games at the highest settings.

The FirePro W9000 has 4096 MB more video memory than the GTX 660, so is likely to be much better at displaying game textures at higher resolutions. This is supported by the fact that the FirePro W9000 also has superior memory performance overall.

The FirePro W9000 has 105.4 GB/sec greater memory bandwidth than the GTX 660, which means that the memory performance of the FirePro W9000 is massively better than the GTX 660.

The GeForce GTX 660 Zotac AMP Edition has 960 Shader Processing Units and the FirePro W9000 has 2048. However, the actual shader performance of the GTX 660 is 1067 and the actual shader performance of the FirePro W9000 is 1298. The FirePro W9000 having 231 better shader performance and an altogether better performance when taking into account other relevant data means that the FirePro W9000 delivers a massively smoother and more efficient experience when processing graphical data than the GTX 660.

The FirePro W9000 requires 274 Watts to run but there is no entry for the GTX 660. We would recommend a PSU with at least 600 Watts for the FirePro W9000, but we do not have a recommended PSU wattage for the GTX 660.

GPU Mini Review

Mini ReviewGeForce GTX 660 Zotac AMP Edition a special edition of GeForce GTX 660.
The new features include a new cooling system and in terms of overclocking, the base-clock was increased from 980MHz to 1046MHz and the boost clock can now reach 1111MHz, instead of 1033MHz. The memory clock was raised to 1652MHz.
Benchmarks indicate a 5.5% performance when compared to the reference card.
FirePro W9000 is a server GPU based on the 28nm GCN architecture.
It's based on the Tahiti XT Core (same used on 7970) and therefore offers 2048 Shader Processing Units, 128 TMUs and 32 ROPs on a 384-bit interface of fast GDDR5. The central unit is clocked 975MHz while the memory clock operates at 1375MHZ.
Compared to Radeon HD 7970, its central unit is slightly higher clocked but overall its gaming performance is lower than Radeon HD 7970 because Radeon HD 7970 benefits from certified gaming drivers which unlock the GCN's architecture potential while FirePro W9000 is made for professional applications. Therefore, expect its performance to be between 1% and 3% worse than Radeon HD 7970.
